Only 54% Full: Air Canada's 10 Emptiest US Routes Revealed [Complete List]

Why It Matters

The weak load factors signal excess capacity and revenue pressure on Air Canada’s U.S. operations, forcing the airline to rethink route economics and potentially reshuffle its North American strategy.

Key Takeaways

• Vancouver‑Tampa route had 54.4% load factor, ending 2026.
• Toronto‑Detroit load factor fell to 59.8%, flights halved since 2019.
• Montreal‑Cincinnati, Toronto‑Charleston, Montreal‑Austin load factors under 64%.
• Ottawa‑Washington fares averaged US$381, double other Ottawa‑US routes.
• Air Canada’s US passenger count dropped >15% year‑over‑year.

Pulse Analysis

Air Canada’s 2025 performance on U.S. routes underscores a broader slowdown in cross‑border travel, driven by lingering political uncertainty and shifting consumer preferences. While the airline still dominates the Canada‑U.S. corridor with a 38% market share, the overall passenger count fell more than 15% year‑over‑year, a rare dip for a carrier that has traditionally benefited from strong business and leisure demand. Load factor—a key efficiency metric—plummeted on several seasonal services, highlighting the risk of over‑capacity when demand forecasts miss the mark.

The bottom‑five routes reveal distinct challenges. Vancouver‑Tampa, a newly launched summer service, never reached half its seats, prompting a full suspension for 2026. Toronto‑Detroit, once a high‑frequency shuttle, saw its flight count cut in half compared with pre‑pandemic levels, reflecting both reduced commuter traffic and competition from high‑speed rail alternatives. Smaller markets such as Montreal‑Cincinnati and Toronto‑Charleston struggled to attract enough passengers despite increased seat inventory, while premium‑priced Ottawa‑Washington flights commanded an average fare of US$381, nearly double comparable Ottawa‑US itineraries, suggesting price sensitivity in the segment.

For Air Canada, these trends force a strategic reassessment of its U.S. footprint. The airline may need to consolidate under‑performing routes, adjust aircraft deployment—potentially shifting from larger 737 MAX 8s to more flexible regional jets—and explore partnership opportunities within the Star Alliance to fill capacity gaps. Balancing network breadth with profitability will be crucial as the carrier seeks to restore growth while navigating a competitive North American market that increasingly rewards data‑driven route planning and agile capacity management.
